392012 ÷ 9 
We want to divide 392012 by 9.

On to step 1:
When dividing 3 by 9, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 9

Moving on to step 2:
If we divide 39 by 9, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 36 from 39, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 9

Advancing to step 3:
9 can be fit into 32 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 27 from 32 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 9

Advancing to step 4:
If we divide 50 by 9, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 435.0
If we subtract 45 from 50, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 9

On to step 5:
9 goes into 51 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 4355.0
Subtract 45 from 51 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 9

Going ahead to step 6:
62 divided by 9 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 43556.0
The remainder is 8 after subtracting 54 from 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 9, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 43556.8
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 43556.88
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 43556.88, and the remainder is 0.008.
